What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRheumatoid arthritis (RA) is an inflammatory disease triggered by chronic and systemic activation of the immune system, with consequences for male fertility. However, the influence of RA on sexual accessory glands remains poorly investigated.
objectivesThis study evaluated the late impact of adjuvant-induced arthritis (AIA) on the morphophysiology of the seminal vesicles and verified whether these effects can be influenced by androgen deprivation. MATERIALS AND
methodsAdult male Wistar rats were allocated into four experimental groups and subjected to induction of AIA (via injection of Mycobacterium tuberculosis in the right hind paw), orchiectomy (ORX), both procedures (ORX/AIA), or neither (SHAM). Forty days after AIA induction, the seminal vesicles were processed for histopathological and morphometric-stereological analysis. Collagen deposition was measured, and immunostaining was conducted to determine PCNA, SVS2, and SVS3 expression. Serum testosterone was determined at 15 and 40 days after AIA induction.
resultsBody mass and wet weight of the seminal vesicles decreased in the AIA-induced and orchiectomized groups, and testosterone levels decreased in the AIA group. Collagen deposition in the seminal vesicle stroma increased in the orchiectomized rats, but not in the AIA rats. Induction of AIA promoted cellular proliferation in the distal region of the seminal vesicles in both intact and orchiectomized rats, and levels of two significant secretory proteins in the vesicle also changed with AIA: SVS2 increased, while SVS3 decreased. Conversely, orchiectomy decreased the expression of both SVS2 and SVS3. DISCUSSION: The late impact of AIA on seminal vesicle parameters appears to be compensated by an increase in epithelial cell proliferation and changes in secretory activity, in an androgen-dependent manner.
conclusionThe data suggest that transient arthritic hypoandrogenism and the direct action of joint inflammatory mediators may influence the seminal vesicle activity. Further research is required to better address the repercussions of arthritis on male fertility.
